home which had a six point checklist of what has to be done at every site before the site is cleared and considered safe. now there is a bit of a time frame. the county really wants to get this work done before the rainy season starts on october 15th. they said once the rains begin then you have additional concerns about drainage an some of this ash going into the creek and eventually out to the san francisco bay. that is certainly on everyone's mind. but if we come back out here live to this scene off of earl avenue here in san bruno. you can see these demolition crews working. they say they're going to take their time. if they pick up a fallen wall and see there's still some momentos or items that are still salvageable they're going to stop that work with the home income back in here and pick up what they can from what is left. crews here are very well aware that this is not just a debris field, this is not just stuff that needs to be cleared. this was once somebody's home. live in san bruno, claudine wong, ktvu channel 2 news. thank you, claudine.
